4.3.3 Online Change Level
The Load module provides you with two ways of online change level. They are
convenient for you to change the load directly with the rotary knob in LOADON. These
two operation modes are described below.
Ratio Mode: In LOADON change load with the rotary knob.
When the rotary knob rotates clockwise, it means as follows.
CC mode: raise the current value.
CR mode: raise the resistance value.
CV mode: raise the voltage value.
When the rotary knob rotates counterclockwise, it means as follows.
CC mode: lower the current value.
CR mode: lower the resistance value.
CV mode: lower the voltage value.
The modulation is dependent on the rotating speed of the rotary knob.
Fixed Mode: In LOADON press the A/B key (single channel/module) or the R/L key
(double channel/module) for at least 2.5 seconds to access this operation
mode. Now V and I will be displayed in fixed positions in this mode.
Press the A/B, R/L, or STATIC/DYNA key to shift a digit left or right. The
resolution nearest that digit will begin to change. The changed digit will
be displayed glisteningly, and modulated by the rotary knob. To exit from
this mode, press the A/B or R/L key for at least 2.5 seconds.
NOTE
: The value of mainframe setting will not be changed if the setting is changed by
the rotary knob. Therefore, when you change the value of setting with the rotary knob,
the value of load module setting and that of mainframe setting will not be the same.
